public interface Duplicatable

This is an alternative to the Cloneable interface without its side-effects. A class implementing Duplicatable provides a deep-copy of itself - usually this is done via a copy-constructor, which is invoked with a self-reference by the copy method. References to child objects are duplicated - references to parents are kept as-is and might need to be replaced by the parent copy operation.
